Question

3c - 2 / 7 - 5c - 8 / 4 = 1/14​

Answer 1

Answer:

3c - 2/7 - 5c - 8/4 = 1/14

LCM of 7 and 4 = 28

3c*28 - 2/7*4 - 5c*28 - 8/4*7 = 1/14

84c/28 - 8/28 - 140c - 56/28 = 1/14

84c - 140c - 8 - 56 / 28 = 1/14

- 56c - 64 / 28 = 1/14

-56c - 64 = 1/14 * 28

-56c - 64 = 2

-56c = 2 + 64

-56c = 66

c = -66/56

c = -33/28
